Does the Bank have any Reg E liability when the cusotmer uses their Visa branded debit card to make a purchase and then it ends up being a scam? The transaction was initiated by the customer so Reg E won't cover them but does the consumer have any recourse since our cards are Visa branded?
There are no Reg E protections here, but your Visa Agreement may require you to pursue a possible claim. The good news is you won't have to follow Reg E's timing or provide provisional credit for the dispute.
Also, is there a difference in Bank and consumer liability when the cusotmer states they just noticed transactions from 3 years ago on their statement versus they state they noticed the unauthorized transactions 3 years ago and never came in to stop them? Would the Bank's liability be the same regardless since we have to go by when they notify us? So Bank's liability would be first unauthorized transaction on the periodic statement plus 60 days in both scenarios?
Consumer negligence, unfortunately, does not increase consumer liability. You're correct, the 1st statement date on which the transactions appear, plus 60. If this is an actual situation, it would be a REALLY good time to exercise your right to refuse another card - and/or maybe even close the account altogether.
